On this week's 'How I Met Your Mother', Ted and Marshall throw Barney the worst bachelor party in the history of time... inviting his sworn nemesis: Ralph Maccio of 'The Karate Kid'. Oh, and his ex-fiancee Quinn.

Synopsis

In 1738, a pact is drawn up between the Alden family and a highly respected Colonial college: If any female member of the family can pass her college exams within a 200-year period, ownership of the institution will be turned over to her. Two hundred years later in 1938, the last of the Alden girls, Gracie Alden hires Bud Brady to help her pass her exams. She also tries to win over no-nonsense professor Hubert Dash, who has no intention of handing his college over to a ditzy young lady like Gracie.
